Description

This is an implementation of ASCIIMathPHP for DokuWiki. ASCIIMathPHP is a PHP port of the brilliant ASCIIMathML standard for easy encoding of math.

It's similar to asciimathml but doesn't rely on JavaScript. Math code must be enclosed by backticks (`e=mc^2`).

Installation and Plugin Code

Create a plugin directory named masciimath and put these files in it:

syntax.php from below
ASCIIMathPHP.class.php from the ASCIIMathPHP download
ASCIIMathPHP.cfg.php from the ASCIIMathPHP download, or use my alternative expanded and bugfixed edition here.
